I like the idea about the hand, but there are a couple of things I find problematic. First, you don't mention looking for any reads on the given hand. It seems that you arbitrarily decided "this" would be the hand for you to make a move. Also, is this the best board for that play? The pair on the flop may scare her, but it's not nearly as bad as a 4458 board or something like that. Do you think she's more inclined to fold because of the relatively tame looking flop? That's certainly a possobility. For the most part I like the idea of using your knowledge to make a well-thought out play, but have to wonder (especially knowing the result) if you were careful enough to choose the best possible time.
